UNITED WILLIAM H. CASLOW. 0F CLARIDGE PENNSYLVANIA.

INSULATOR.

To all whom it may concern Be it known that I, WILLIAM H. CAsLow, a citizen of the United States, residing at Claridge, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Insulators; and I do hereby declare the following to be a full, clear, and exact description-of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. f

This invention relates to insulator suptelephone wires, trolley wires, and the like, andin particular for a means of fastening the wires in said support without the use of a tie wire.

The main object of this invention is to give a device whereby the wire is fastened into the insulator in such manner that the wire has free longitudinal play therethrough.

A still further object of this invention is v to give a device whereby the insulator with the wire fastened therethrough has free horizontal and vertical play within a certain radius; And a" still further object of this invention is to give a device whereby a plurality of wires can be supported from one cross beam structure.

Other objects and advantages of this invention will be hereinafter more clearly set forth in the specifications and pointed out Similar characters of reference refer to similar parts throughout the drawings, in which, l 1

Figure 1 is an elevation of the upper end of a pole showing a plurality of insulators attached thereto. Fig. 2 is an enlarged elevation of one of the insulators and its support. Fi 3, is a sectional view looking at right ang es to that shown in Fig. 2, through one of the insulator supports. Fig- 4, is a sectional view at right angles to that shown in Fig. 3. I

In the drawings, 1 is a pole or other suitable form of support to which is bolted or otherwise suitably fastened as at2, a cross beam 3. .Vertically mounted through the end portions of said beam 3 are hollow standards 4 and '5 respectively, said standards being adjustabl mounted through said beams 3 by means 0 adjusting nuts 6 and 7, nut 6 being above the beam and nut 7 below the beam. The standards have suitable transversely extending slots 8 therethrough Specification of Letters Patent.

Application filed. August 13, 1914. Serial No. 856,578.

as seen in Fig. 4 through each of which is mounted a supporting rod or bolt 9, said rod or bolt having an inside face plate 10 and an outside face plate 11 adapted to play,

against the walls of the standards 4 and 5 to retain the member 9 in proper positionand yet allow suitable horizontal movement according to the strain upon the wires 12. This arrangement allows of a lateral and rotary movement of the member 9 when mounted in this manner to compensate for lateral movement of the wire at one end of the support.

Suitably fastened to the head portion 13- of the member 9 is a sleeve like bracket device 14, said sleevelike bracket device being fastened to the head 13 in countersunk formation. The retaining member 15 is mounted within the sleeve like bracket 14:, 1

said retaining member being formed of insulating material but preferably of. glass or porcelain. A portion of the face surface is grooved as at 16 and is adapted to seat a.

said bracket 14 as plainly shown in Fig. 4

.so that the outer face 17 of said member 15 is formed flush with the outer surface 18 of said bracket 14. This arrangement allows of a rotary movement of said member 15 within the bracket 14 and yet will retain said member 15 from falling out of the bracket. Extending longitudinally through the member 15 is a slot 19, said slot-running from the periphery toward the center in an approximately ser -pentine' formation, the outer end of which starts from a depending point and the inner of the member 15 in end of which ends in a depending manner. 1 The member 15 is rotated so as to bring I the outer end of the slot 19in registry with the slot 20 formed in the bracket 14. The wire is then inserted throu h the slot 20v of the bracket member 14; an the member 15 until it reaches the inner end thereof, as shown at 12 in'Fig. 3. The member 15 is then slightly rotated to break the ,registry of the slot 19 with the slot 20, there by locking the wire 12 within the member 1.5

against loss, and yet allowing of longitudinal movement therethrough. As an additional precaution against displacement of the wire 12 from the slot 19, a wedge member 21 is suitably seated in a transverse slot 22 across the slot 19, thereby additionally locking the wire from displacement, as

plainly shown in Fig. 3.

Although I have shown but two of themsulator supports and one cross beam for supthe slot 19 of v porting the same, it will be readily understood that any number of supports and cross beams may be employed as the occasion may require.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. A wire supporting device comprising a hollow standard having transverse slots therein, supporting rods having their inner ends extending through said slots, face plates engaging the rods on opposite faces of the standard, brackets carried by the outer ends of said rodsfsaid brackets having longitudinal slots therein, retaining members of insulating material having circum-. ferential grooves to receive said brackets, and means to engage wires with said retaining members.

2. A wire supporting deviee' com rising a hollow standard having transverse y disposed slots therein, a rodextending through each slot, face plates on the rods on opposite faces of the standard, brackets secured to the outer ends of the rods and having slots extending longitudinally thereof, retaining members of nonconducting materialadapted to be secured in said brackets, said retaining members having circumferential grooves to receive the brackets, said retaining members having slots formed therein and extending in substantially serpentine formation from the outer edges of the retaining members to the central portions thereof, each end of the slots being at a plane below the.horizontal centers of the retaining members when in normal position.

3. A wire supporting device comprising a hollow standard having transverse slots thei'ein, a supporting rod for each slot, face plates engaging the rods on opposite faces of the hollow standard, brackets carried at the outer ends of the rods having longitudinally extendin slots, retaining members having circumferential grooves to receive said brackets and embed the same therein to bring the outer faces of the brackets flush with the outer faces of the retaining members, slots formed in the retaining members and extending in substantially serpentine formation from the outer faces of the retaining members to a point adjacent the axial centers thereof and wedge members adapted to extend longitudinally of the retaining members to confine wires in the closed ends of said slots, said retaining members having transverse slots at each edge of the wire receiving slots to receive the edges of said wedges.

In testimony whereof I have name to this specification in the two subscribing witnesses.
